In summary, Murata’s MEU1 series of ultra miniature single isolated output 1W DC/DC converters. Measuring just 8.30mm x 6.10mm x 7.55mm, achieves a 26% footprint reduction when compared to previously released products. The reduction in converter volume and footprint allows engineers to reduce the overall dimensions of the application, which is critical for space-constrained designs. Available as through-hole mounting with staggered style pinouts, the MEU1 achieves a 25% increase in power density and can deliver its output power over the whole temperature range of – 40°C to 85°C. Conversion efficiency has also been improved by typically 6% across the full load range compared to previous models. Efficiency improvements contribute to lowering the overall system power consumption, in addition to increasing system reliability. The MEU1 series also has load regulation that is typically 3% better than the industry norm when compared to similar miniature through-hole converters. This reduces the need for any additional external regulation components and further conserves precious board space. A total of 14 models are available across the series, catering for the popular input voltages of 3.3, 5, or 12VDC and providing outputs of 3.3, 5, 9, 12, or 15VDC. 1kVDC galvanic isolation aids reduction of switching noise and allows the converter to be configured to provide an isolated negative rail in systems where only positive rails exist.
